Considering the growth in population, the need for wood consumption also increases. The rapid progress of science and technology doubles the wood consumption, which needs supply, and at a glance, mainly from the forests. Forests for many reasons have faced decrease in production despite this extreme needs for wood. Given the problems of indiscriminate harvesting of wood from the forest to be continued, strategies for sustainable supply of raw materials for forest products industries should be considered. In this study, to determine a reliable solution the analytic network process for decision making with benefits, opportunities, costs and risks is used. The preliminary results show that combined alternative strategies are more preferred to the other alternatives.

This paper is based on an empirical study of two interior design projects manager in a pair of quite similar (side by side) decoration projects. The purpose of this study is to develop an operative strategy for project risk management using Analytic Network Process. In this research we did an investigation on how group decision making influences managing risk in such a project. This was a rare occasion where the inputs, as opposed to the outputs, of the risk management process were examined. More problematically, the precise nature of the inputs does not seem to have been explored adequately in the previous researches. In this research, seven decision making models are designed for different phases of projects. The effect of dictatorial management approach and a group management approach on the risk management are compared. Comparison of the status of the projects run by the two decision making approaches showed significant differences between their cost and the duration.
